Abstract
A moisture presence alarm system has a sensor system which extends over an area to be monitored and a detector device which receives signals from the sensor system. This has spatially separated conductors in conductive contact with a moisture absorbent material. The position of the leak is determined by selective interrogation of pairs of conductors. The conductors may be in an orthogonal matrix (A1...X1; A2...X2), each conductor (10, 11) being associated with a moisture absorbent strip (12, 13).
